RAISINQCLEANING MACHINE.

To alt whomit may concern:

Be it known that I, INMAIVTUOKER, a

citizen of theUnited States, residing at Yuba City, in the county of Sutter and State of Calif, have inventedJcertain new and,

useful Improvements in Raisin-Cleaning Machines, of which the following isaspecification. I

This invention relates to improvements in machines for cleaningaaisins and the like, and more particularly to the: type of machine embodied in Patent No. 1,170,026, February 1, 1916.

The obj ect of the invention is to simplify the construction and operation of certain component parts of themachine.

To the accomplishment of the recited object,:and others coordinate therewith, the

preferred embodiment of my inventionresides in the construction and arrangement of parts shown in the accompanying drawings, hereinafter described and embraced within the scope of the appended claims.

In said drawings:

Figure l is aside elevation, partly in section, of the complete machine.

Fig. 2 is a fragmentary perspective View of the toothed combing and elevating bar.

Fig. 3 is a view in perspective of the sustaining bar for the guide rods.

Figs. 4 and 5 are sectional views of modifications.

Fig. 6 is a detailed perspective of a portion of the toothed bar and shaft.

And Fig. 7 is a detail perspective view showing the tooth reversed.

In my original application there is disclosed a plurality of individually operable combing and elevating fingers, which by means of certain tripping mechanism have imparted to them a slight kick. As explained in the specification this kick combined with the force of the airblast serves to carry away theforeign particles over the edge of the butting board. I have found that by slightly increasing the force of the .air blast and eliminating the kick together with the mechanism used to produce such movement of the fingers that all extraneous matter can be separated from the raisin pack very satisfactorily, thereby effecting considerable saving in parts as Well as reducing to a minimum the likelihood of the ma chine becoming inoperative. I have devised three simple ways in which this result may be accomplished,and in each instance the Specification of Letters Patent.

Application filed January 4, 1916. Serial No. 70,222.

combing and elevating teeth are fixed or rigid and operate as a unit w1th respect to the foraminous cradle which contains the raisin pack. a

In the drawings, 5 represents the frame, 6 the conveyer leading to the hopper 7, 8 the foraminous cradle and 9 the blower provided with a spout 10, all of which parts are specifically described in. my original application. Referring particularly to Fig. 1, it will be seen that I mount a reversible eccentric shaft 11 transversely of the frame 5 above the hopper 7. Loosely fitted to and depending from the opposite proximal ends of the shaft are a pair of hangers 12 which are rigidly connected to the guide rods 13 at their lower extremities. These rods support a transversely disposed bar 14 carrying a plurality of teeth 15, and at their upper free extremities operate in slots 16 of the sustaining bar 17. When motion is imparted to the pulley 18 of the shaft 11, the rods 13 serve to guide the toothed bar 14 and at the same time cause the teeth to describe an ellipse.

In Figs. 5 and 6, the guide rods are eliminated entirely and the toothed bar 14 is secured upon one side of a straight shaft 19 supported by the depending bearings 20. Bolts 21 or equivalent fastening means may be used as fastening means; In this modification the sweeping movement of the teeth is made possible by the eccentric location of the bar relative to the square shaft.

The modification exhibited in Fig. 4 comprises a drum 22 provided with peripherally arranged teeth 23 mounted in the bearings 20. This form is devoid of any means for efi'ecting a sweeping movement, but in all of the forms it will be seen that the teeth are curved at their lower extremities, and are adjustably attached so that they may be reversed to correspond with the direction of rotation of the shaft.

In operation the cradle is reciprocated in a horizontal plane, thus alternately forcing the pack of raisins rearwardly and for wardly of the cradle. timed that the teeth, when rotated, will operate'upon the pack while it is disposed rearwardly of the cradle, combing and ele- The mechanism is so butting board or end of the chute 24, where the foreign matter is blown by the blast issuing from the spout 10 and passing through the uncovered perforations in the front of the cradle over the end of this butting board.

Under some circumstances, I have found that it is highly desirable to reverse the direction of rotation of the shaft so that the material to be acted upon Will be carried toward and in direct opposition to the air blast, thereby effecting a more positive sep aration of the foreign matter, and the like.

In this case, the position of the teeth may be reversed to facilitate the operation.

WVhat is claimed is: 1. In a machine of the class described, the combination of a fora'minous cradle adapted to hold raisins, or the like, to be cleaned, means for causing the raisin pack 2. In a machine of I the character described, the combination of a foraminous cradle, means for agitating said cradle, a reversible shaft disposed transversely above and adjacent said cradle, reversible teeth movable as a unit With said shaft, and adapted during a portion of their movement to operate Within the confines of said cradle, and means for supplying an air blast to said cradle.

3. In a machine of the H character described, the combination of a foraminous cradle, means for agitating said cradle, means for supplying an air blastto said cradle, a shaft disposed transversely above and adjacent said cradle, combing and elevating means associated With said shaft and operable in the cradle in a direction opposed to the direction of said'air blast.

In testimony whereof I hereunto affix my signature in presence of two Witnesses.
